Most of the other weakness you wrote can easily be fixed with you posting hands. We will start writing feedback to your play. And usually negative feedback will put you into thinking phase and trying to fix all those leaks. It's almost the same as you loose money, you will remember it more than winning part.

Thinking too much about your money might even cause all those problems what you wrote down. If you are stick too much to money then you get money-scared and then might turn too passive or rather too nitty.

Very good approach to play rather according the chart if you are rather new to poker. I'd just say that at the beginning we don't need to widen up our range anyways. We just gonna face too many difficult spots where we gonna loose too much money in long run rather than earn.

About Question #3:
There are few situations on turn:
a) If we take just odds for the FD and we take into account that all our odds are clean. There which means:
Total Pot = $0,91 ; We have to Call = $0,22 -> According to that it means we are getting ~4,16:1 odds. For flushdraw we would need 4:1. Which tells us that we are getting perfect odds.
b) If we consider the opponent having sets here:
Which means we have to discount outs, for example 6 and also 3. Which means we have 7 clean outs. Which means that we need 6:1 odds. That tells us that we need ~$0,41 on river to make it profitable. If we expect the opponent being loose enough and being able to pay us no-matter what then we can do the Call here properly.
c) We might even have overcards as outs or even 4 as a out:
Although this kind of situation ain't that likely. I'd rather discount that one and either pick a) or b). Most likely towards Call.

This weeks homework was a bit easier. But the idea of that is to help you go through last weeks stuff if you didn't go through everything. Or either way maybe even read some more articles, watch some videos and of course attend in the coaching. What will also help for your game is the evaluation part of other members hands and of course posting your own hands.

Hopefully this wasn't too easy homework for you. Some more points earned.

About Task #3
It's a very close decision: does protection or pot control weigh heavier here? Do you want to protect against hands like 3x or A:dx and K:dx? Or do you want to control the pot size and try to induce a bluff on the river in case there is no T, no J and no additional ?

Raise/fold is out of question - with the given pot size and the good made hand you have, it can't even be considered.

In case you decide to go broke, you can't really be blamed either. It's not a sign of weakness that the rather tight small blind decides to bet into two people here, though. I would say a call is to be slightly favored, while the many outs against you are annoying. The big blind who calls rather loosely speaks in favor of a raise/broke again. Both options are finally considered equal, which shows - all things considered - how close and full of variance these spots really are.

About Task #4
You've called pre-flop and then hit a good board. You basically have two choices now: either you assume that your opponent will go broke loosely or puts you on a bluff often and you thus check/raise - or you play check/call in the spirit of way ahead / way behind. The problem with the latter is that there are a lot of cards you don't want to see in the later course of the hand. All in all, it depends on your balancing as both lines make sense under certain circumstances.

A check/fold would be really pointless, of course. It's hard to say whether you should donk-bet here; donk/fold can be discarded as that would turn your hand into a pure bluff and your opponent would interpret this as weakness and start raising you out of flops with hands like AK/AQ/air. So, if you want to donk-bet, it has to be a donk/3-bet.
